Email Firewall
A set of features of Symantec Mail Security that provide perimeter defense, similar
to a regular firewall, focused on email traffic. The Email Firewall analyzes incoming
SMTP connections and enables preemptive responses and actions before messages
progress further in the filtering process. The Email Firewall provides attack
preemption for spam, virus, and directory harvest attacks, and sender blocks
based on IP address, domain, third party lists, or Symantec lists.
email server
An application that controls the distribution and storage of email messages.
encrypted attachment
A message attachment that has been converted into a form that is not easily
understood by unauthorized persons. Symantec Mail Security does not scan
encrypted attachments, but allows you to choose an action to take when an
encrypted attachment is detected.
Ethernet
A local area network (LAN) protocol developed by Xerox Corporation in cooperation
with DEC and Intel in 1976. Ethernet uses a bus or star topology and supports
data transfer rates of 100 Mbps.

Symantec Mail Security.
filter
A method for analyzing email messages, used to determine what action to take
on each message. Symantec Mail Security uses a variety of types of filters to
process messages. A filter can be provided by Symantec, created by a local
administrator, created by an end user, or provided by a third party.

Filtering Hub
A component of a Symantec Mail Security Scanner that manages message filtering
processes.
filter policy
In Symantec Mail Security, a set of actions that apply to a category of messages.
The actions specified in a filter policy are only applied to users who are members
of a Group Policy that includes the filter policy. There are three types of filter
policies: spam, virus, and content compliance policies. Filter policies can also
make use of policy resources. See also Group Policy, policy resources.
firewall
A program that protects the resources of one network from users from other
networks. Typically, an enterprise with an intranet that allows its workers access
to the wider Internet will want a firewall to prevent outsiders from accessing its
own private data resources. See also Email Firewall.
